Ipomoea trifida is considered as a wild crop relative to sweet potato Ipomoea batatas. A set of 10 accessions was selected for tubered-bearing I. rifida originated from Citatah West Java was evaluated on their diversity based on chromose traits. A field trial and laboratory analysis were conducted at Universitas Padjadjaran Bandung Indonesia. Relationship between species identified by cluster analysis and Principal Component Analysis (PCA). The results showed that the observation on the 10 accession of tubered-bearing I. trifida using nine chromosome traits produced dissimilarities distance (Euclidean coefficient) ranging from 1.75 to 6.22. Dendogram generated at a dissimilarity distance of 5.23 showed the formation of three main clusters. Principal Component Analysis (PCA) produced first two principal component (PC1 and PC2), which has been able to explain 89.64% of the total variation. It is concluded that thare are highy diveristy between 10 accession of tubered-bearing I .trifida based on chromosomes traits.
